The invention provides a method and a device for measuring total organic carbon in waterbody. The method for measuring the total organic carbon in waterbody comprises the following steps of: detecting the waterbody in an experiment pool to obtain voltage signals corresponding to the organic carbon in the waterbody; performing integration processing on the voltage signals to obtain area values corresponding to the voltage signals; and calculating the concentration of the total organic carbon in the waterbody according to the area values and the preset concentration formula, wherein the preset concentration formula is the linear relation formula between the concentration and the area values. The concentration of the total organic carbon in the waterbody can be accurately and reliably obtained by detecting the waterbody in the experiment pool to obtain the voltage signals corresponding to the organic carbon in the waterbody at different moments, then performing integration processing on the voltage signals to obtain the area values corresponding to the voltage signals and finally substituting the area value in the concentration formula. The invention improves the reliability of the method for measuring the total organic carbon in the waterbody as the detected voltage signals need not to be supposed to be stable or time-invariant.
Description
technical field [0001] The invention relates to the field of measurement technology, in particular to a method and device for measuring total organic carbon in water bodies. Background technique [0002] At present, the total organic carbon (Total Organic Carbon, hereinafter referred to as: TOC) in water bodies (for example: oceans, lakes or rivers) is a comprehensive indicator of organic pollutants in water bodies, and is one of the most important items in marine environmental monitoring, because TOC is The carbon content is used to represent the comprehensive index of the total amount of organic matter in the water body, so TOC can more directly and reasonably express the degree of organic matter pollution in the water body. In the prior art, the measurement technology of TOC in the water body is usually carried out on the laboratory platform, specifically: assuming that the signal corresponding to the TOC in the water body is stable or time-invariant, and then calculating...
